Does anyone that has the Horus Heresy Betrayal Book know if the stuff in there can be used with regular 40k lists in an Apocalypse setting, that is, is it all the same type of rules and stat lines, etc.? Is it worth the over $100? I would hope it's a good read too, looks like lots of neat pictures and diagrams.

Also, can Chaos use that Cerberus anti-tank neutronic style laser land raider looking thing? I saw on the FW site it said "..... It would not be long, however, before the Cerberus was called upon to turn its destructive capacity against the Imperium’s own..."
